In pervious soils, the <br />indicated elevations are considered reliable grpurui water levels. In impervious soils, the acairate determination of ground <br />water elevetiont is not po»iblt in even aeve ai days observation, end edditional evidarKt of ground water elevations rmiit <br />be aought. <br />GRADATION DESCRIPTION & TERMINOLOGY: <br />Coarse Grained or Granular Soils have more than 50% of their dry weight rareined on a ^200 sieve; they are described as; <br />bouldefB, cobbles, gravel or sand. Fine Grained Soils have lass than 50% of their dry weight retained on a ^200 sieve; they <br />ere described as: clays or clayey silts if they are cohesive, and sifts if they art non<ohesive. In addition to gradation, <br />granular soils are defined on the basis of their relative in place density and fine grained soils on the basts of Chair strength or <br />consistency, end 'hair plasticity. <br />Major <br />Component <br />Of Semple Silt Range <br />Descriptive Tarm(s) <br />(Of Components Also <br />Present in Sample) <br />Percent of <br />Dry Weight <br />Boutdtrs Over 8 In.
